ruby - Insert information from hash into iteration -


i trying insert information hash monthly_multipliers iterator.

month_multipliers = { april: 1, may: 2, june: 3, july: 4, august: 5, september: 6, october: 7, november: 8, december: 9, january: 10, february: 11, march: 12} months = ['april', 'may', 'june', 'july', 'august', 'september', 'october', 'november', 'december', 'january', 'february', 'march']

i iterate through each month, , need inject monthly multiplier each month, june 3 august 5 etc.

months.each |month|   instance_variable_set :"@#{month}_income", (monthly_new_account_income * month_multipliers[month]) + previous_years_monthly_income end

this bit doesn't work

 month_multipliers[month])

i tried sending , getting instance variable, cannot format right.

month_multipliers has keys in symbol objects, months has keys string objects. use either symbol or string objects or convert keys correct object before retrieving values hash.
